Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The influence of static helical perturbations on high-energy ion motion in tokamaks is investigated. Numerical solutions of drift motion equations are in good agreement with analytic estimations of the critical amplitude value that is sufficient for destruction of drift surfaces. Three types of perturbations are considered: large-scale helical modes with wide regions of localization comparable with the plasma column radius, small-scale modes localized near the resonant magnetic surfaces, and balloon-like modes. For all three cases, high perturbation amplitudes are needed for destruction of drift surfaces. The static helical perturbation does not appear to lead to noticeable high-energy particle losses in tokamaks until the perturbation amplitude exceeds the value sufficient for magnetic surface destruction.
